If a company wants to use python in a commercial project and does not want the source code to go public (i.e closed source ). How would one go about packaging the python project.

Is there something similar in the python world like a jar file ? Or you could write the secret sauce part of the application in something like Cython and compile it into a SharedObject/DLL and use it as a library from your python code. This has the dual advantage of obfuscating your python code as binary and getting performance boost of a compiled language.

You mean what's the need for using lambda functions? Lambda functions are anonymous functions, ie., functions without a name. Along with map, reduce, filter, lambda functions provide functional programming[1] constructs to python. You can write code like this: from operator import add print reduce(add, filter(lambda x: x%2==0, xrange(10))) to print the sum of even numbers less than 10 instead of: tot = 0 for i in xrange(10): if i%2 == 0: tot += i print tot ... Anyway, One does not need to use lambda function. Almost in all the places where you use lambda functions, you can replace it with a named function with added benefit of clarity. Python lambdas are limited to a single statement, which makes them particularly hobbled. Guido is not very fond of FP constructs, in fact he wanted to remove them from python 3. After much discussion, lambda survived in Py3.

Many thanks for the patience to read this. Looks like you and many in your team desire a desktop like behaviour.. So, as Noufal suggested it is better to create web services which query the backend(perl scripts, database etc.,) and provide data to clients in json/xml format. It is easier to code drag and drop like behaviour in a desktop widget than in a web app, especially if you are not a javascript/ajax expert already. It appears you may be building an app for in house use, may be even something to do with sys administration and reporting. In which case, the look and feel of tcl/tk, which has improved by leaps and bounds in 8.5, should not be a huge concern. However, If you want to have near-native UI look and feel and also have a modern widget toolkit, take a look at PyQt or wxPython. To answer your other questions in particular order, * web.py can be run with apache using mod_wsgi and mod_python and of course mod_proxy. * The equivalent of vaadin would be Pyjamas, which is a port of GWT to python.

I was thinking of using Django framework. Btw i'm relatively new in python. Woud anybody please suggest whether Django is a good candidate for this. I succesfully installed Django and worked with some sample codes. Is there any similar framework which is more reccomondable than Django. Atleast this time i want to get this done with python. Many times i wanted to do things in python for some reason or other reason i was forced to use some other technology. I have some doubts like 1. Django sample webserver cannot be used when it's mission critical? Will this django framework supports apache or tomcat servers. 2. Certain query results i would like to display in graphs. I had mailed before asking suggestion for creating charts/bar/pie graphs with python and got a good number of suggestions like pychart, pygoogle chart open flash etc. I was just thinking how difficult is to integrate these stuffs in Django framework. Also couldn't actually finalize a good framework to use for creating this graphs. I'm absolutely in confusion which'll be better to use. Would anybody suggest what's the usual thought process in taking decisions like this. Django is an overkill for something like this. web.py is what you should be looking at. If you already are programming in python, web.py will give you the web library without trying to introduce new concepts on URL dispatch, ORM etc., Web.py has a very decent db api for most common db operations You can fall back to raw SQL with ease. ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

The work is far from being mission-critical is another point altogether. That's because big boys define the market suitable to themselves. 1. it's easier to code more, take more time when using proven technology 2.

A good IDE is a massive productivity booster; you can only get so far with a text editor*, no matter how many macros you have set up. Honestly. My riff was on the monkey part, not on the IDE part. A programmer who uses IDEs for refactoring etc., is a more evolved primate, IMO ;) The bogus argument about proven technologies often stems from the belief that having a point-and-click-and-get-a-banana is a proof of maturity or enterprise-readiness . Platforms which are heavily IDE centric (eg: MS technologies) tend to encourage their developers to think inside the box (IDE) all the time. Even though most Java programmers do use Eclipse/Netbeans/IntelliJ it is not unheard of them to use vim/emacs more often than you hear a .NET developer using them. IDEs have their advantages. But more often than not, they also hide complexity behind all the boiler-code and templates.

(resending reply to the list.. ) Python uses indentation for blocks your code has uneven indentation(1 space?) and no indentation in some places. You have to indent code correctly.

Re: [BangPypers] how to learn programming
Hopefully this scientific study with hard numbers conveys what I was saying in my earlier mail about Python being a better choice for learning vocational programming. This is the summary of a talk accepted for PyCon 2009. http://us.pycon.org/2009/conference/talks/ Python for CS1 Not Harmful to CS Majors (and good for everyone) Dr. Bill Punch (Michigan State University) bio; Dr. Richard J Enbody (Michigan State University) 30min Intermediate education At Michigan State Computer Science Dept. we have recently converted our CS1 course (200 students/semester, about 60% non-CS majors) to Python, previously taught in C++. Follow on courses for CS majors (CS2, etc.) still use and teach C/C++. Right around the conversion point, we had two groups of students taking the C++ CS2 course: those that took CS1 in Python and those that took CS1 in C++. We examined the performance of those two groups of students in the CS2-C++ course (covering the same topics as previously), looking for any significant differences as measured by t-test with respect to: final exam grade, overall programming project scores and final course grade. No significant differences between CS1-Python and CS1-C++ were found. Further, multiple regression analysis showed that only GPA was a good predictor of the three outcomes. Neither CS-1 Python nor CS1-C++ was a predictor. Our conclusion is that a CS1-Python course was as good a preparation for a CS2-C++ course as was a CS1-C++ course. Furthermore, CS1-Python was a far better terminal course for non-majors than CS1-C++, and both majors and non-majors were could address a wider range of practical STEM problem than previously. We have written a CS1-Python book for others who wish to teach a Python-CS1 course that emphasizes teaching Python to CS1 students with a theme of data manipulation. +PG On Sat, Jan 24, 2009 at 10:07 PM, Roshan Mathews rmath...@gmail.com wrote: On Sun, Jan 25, 2009 at 2:56 AM, Sridhar Ratnakumar sridhar.ra...@gmail.com wrote: On Sat, Jan 24, 2009 at 7:46 AM, Roshan Mathews rmath...@gmail.com wrote: The 'knowing the rules' vs. 'being proficient' argument is also made in SICP http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-11.html#%_sec_1.2 ... another good read, (Indian version of the dead trees version available from University Press.)

I've written a python library to generate data files used by the excellent open Flash chart 2.

Complete. I've implemented python wrapper classes for all chart types and elements. 2. Pythonic. The original PHP library uses setters and getters for properties etc., 3. Demo charts. Each chart type has a `test_ foo` function which shows the usage. 4. Test coverage. 5. No dependency on any python framework. The default distribution uses Cherrypy. Programming notes: This is also the first time I used python meta classes. The test cases are also used to generate the demo files you see on the website.

Re: [BangPypers] how to learn programming
Learning programming via C will force you to understand data structures like lists, queues and hash tables better purely for the reason that C does not provide them in the standard library. C++/Java/Python do via STL and standard libraries respectively. Generalizing C++ with C shows how misunderstood C++ is. C++ is not C with stuff bolted on. Teaching C in the first year of engineering compared to a language like Python, Lua or Ruby is a sure way of turning off students to the joys of programming. Not everybody needs to know how to implement a linked list and a queue. A vast majority of technical graduates go on to do programming either as software developers and/or engineers in other streams do NOT have to do low level programming. If they were taught to solve problems using a dynamic language like Python/Lua/Ruby instead of twiddling bits, we would see newer applications being built by non-CS graduates in their domains. Oh well, why would CS professors be concerned about productivity. A lot of my mechanical engineering classmates(who were bright students) where scared to death of FORTRAN and C, because C made it so difficult to do simple things like Computer Graphics (which is what they wanted to accomplish in the CAD lab). A library like Pygame would have allowed them to write CG apps and CAD programs without racking brains about C and pointers. +PG On Fri, Jan 23, 2009 at 10:22 AM, prasanna diwadkar pdiwad...@yahoo.comwrote: I was talking in general.I am not saying python/java programmers are lesser quality than C/C++ .Ultimately programming is a programming is a programming.

Don't confuse the lack of sophistication of their website with any lack of sophistication in engineering. Space rocket science/engineering is a much more complex and delicate affair than typical software engineering. ISRO develops and uses complex software for mission control which is not exactly akin to developing a website - it is much more difficult to get right. Even if your website crashes, perhaps you might loose data or a few visitors and lose some uptime. However, this is not the case with the software used in space science. Everything has to work and work perfectly. Remember that simple software glitches have often caused entire rocket missions to be aborted. This has happened even for mighty NASA. The most recent one I can think of is the glitch with VxWorks that happened in one of their Mars rovers which caused the system software to reboot itself many times. In fact ISRO has done a splendid job managing to put a satellite to Moon orbit and also perform a moon impact all in the very first attempt. Recall that Russia and U.S.A have had several crash lands and aborted attempts in their moon missions. The quality control at ISRO has to be pretty damn good. I read a few articles about the images from Chandrayaan and it seems the camera they have is top-class. The images it has send are already pretty good, and it is perhaps the first moon satellite to carry a 3D (Terrain mapping) camera. I don't think any single moon (or perhaps earth) satellite is a classic example of international co-operation. Chandrayaan carries 11 payloads. To me, it looks like India is leading the way in international space co-operation. ISRO needs a big pat on the back for what they have done.

Re: [BangPypers] One python question (from verilog)

The equivalent python code would be*:

matched = 0
while matched != 1:
read_data = read_reg(reg_offset)
if read_data[bit_pos] === poll_val:
matched = 1
else:
matched = 0
return matched
* Implementing read_reg is left as an exercise to the developer :p
I'm not aware of any python library methods which allow one to access
registers. But, the read_reg() can be implmented in C and
imported into Python.
Any low level operation like register access is usually delegated to .

Notepad is the most useless piece of software that ships with windows. I use Textmate and aquamacs (both on mac of course) and vim occasionally. For a windows new user, I recomment SciTE (which is also available via pywin IDE). I recommend it to every new student of mine and so far, I've heard no complaints. Some of them have switched to vim/emacs etc.,. But to start with SciTe is the easiest. Its super-light weight, supports lots of languages, is cross platform. An editor like SciTE which understands python, makes the space is signiicant mental block a little easy for the newbie. Also, SciTE has an easy shortcut F5 to execute code, the result of which can be seen in split window. This also makes it attractive for write-test interactive mode.
